What Is Post-Quantum Cryptography? A Practical Guide to Future-Proofing Encryption

In August 2024, the National Institute of Standards and Technology (NIST) released its first three finalized standards for post-quantum cryptography (PQC)—a milestone that marks the beginning of a global transition to quantum-resistant security. While these standards run on classical computers, they’re designed to protect against a looming threat: the cryptographically relevant quantum computer (CRQC). A…
